I am considering pivoting to interest only loans with a refi plan.

We are having a difficult time finding a property manager in the area so we are trying to work on a contingency plan should we have to manage it from afar. 

Just be honest and tell her you are planning on selling and want the home vacant, so she needs to move. 

I'm now planning on growing via small hotel/motel projects and overlooked  non-hospitality commercial. 

Option 2 - We currently have ~$50k cash on hand and would plan on saving another 30-50k over the next 12 months.  

Big swings are not for me.I was planning to borrow against my investment portfolio at 5%, then invest that money in fractional TDs. 

@Chao Yi Shih hi my main concern here is that if you didn’t get a real inspection it sounds like you don’t plan to get insurance on it.

Usually without any hesitation.However, be ready for the valuation to jump back up the following year as you will have to prove next year that the house is not worth what they will adjust the property value.  

As a option, instead of a commission structure, you can put them on a bonus plan and provide payouts based on a set of criteria. 

I wouldn't plan on interest rates going down much, act on what important now.
